The basic structural unit of an element

Which is not a subatomic particles found in an atom?

• neutrons

• electrons

• protons

• ions

a subatomic particle that possesses a negative electrical charge and the smallest in terms of mass among the 3

• neutrons

• electrons

• protons

• ions

a subatomic particle that possesses a positive electrical charge

• neutrons

• electrons

• protons

• ions

a subatomic particle that has no charge

• neutrons

• electrons

• protons

• ions

protons and electrons carry the same amount of charge

• True

• False

both protons and electrons are massive particles compared to neutrons, they are almost 2000 times heavier

• True

• False

Answer explanation

both protons and NEUTRONS are massive particles

all protons and all neutrons present found at the center of an atom in a very tiny volume of nucleus

• True

• False

how to get the number of neutron?

• Mass number - Atomic number = neutron

• Atomic number - Mass number = neutron

• Atomic number - proton = neutron

• Mass number - proton = neutron

This is the sum of proton and neutron.

• Mass number

• Atomic number

• Mass size

• Atomic size
